没有在标志Bukkit上显示的球员名字

Question

我对bukkit很新，但我不明白为什么会这样。玩家名称不会使用bukkit显示在标志上。之前有用，但我不知道我做了什么阻止了它的工作。我正在使用插头1.9。使用＆＃39; Bukkit.broadcastMessage（）＆＃39;显示播放器名称。但是。

以下是我的代码的一部分：

if (cmd.getName().equalsIgnoreCase("sign") && sender instanceof Player){

    Player player = (Player) sender;
    Location location = player.getLocation();
    World someWorld = Bukkit.getServer().getWorld("world");

    double playerx = location.getX();
    double playery = location.getY();
    double playerz = location.getZ();

    int px = (int)playerx;
    int py = (int)playery;
    int pz = (int)playerz;

    Location nLoc = new Location(someWorld, px+1, py+1, pz);

    Location sLoc = new Location(someWorld, px+1, py+1, pz-1);


    Block block = someWorld.getBlockAt(nLoc);
    block.setType(Material.WOOD);

    Block block1 = someWorld.getBlockAt(sLoc);
    block1.setType(Material.WALL_SIGN);
    Sign sign = (Sign) block1.getState();
    sign.setLine(0, "Hello "+player.getName());
    sign.setLine(1, "Welcome To My");
    sign.setLine(2, "Server!");


    Bukkit.broadcastMessage("Name: "+player.getName());
    sign.update(true);
